Re: Wiring diagram house/starter bank needed
For an EchoCharge to maintain a separate windlass battery properly, you'd still have to use pretty large size wires to avoid excessive voltage drop over long runs. It's do-able, though.
I chose a different route: I have two T-105 Trojans under my V-berth forward which power the windlass. These are charged by an Iota DLS-55/IQ4 battery charger also located in the forward cabin. The charger is powered either from shore current or from my onboard 3.5KW AC generator. In an emergency, it could also be powered from my Victron Multi-Plus 2500 watt inverter, drawing current from the house batteries (six T-105s).
Even without charging, I think the T-105 pair have enough oomph to operate the windlass (Lewmar Concept 2) for at least 5-6 anchoring cycles -- both down and up.
This system has worked quite well for many years now. I chose this solution because I like very often to come to anchor under sail, and to sail off the anchor without the engine running. As MaineSail says, the house batteries do a very good job of powering the windlass without the need to start the engine.
